Flight
Miami International Airport (MIA) is closest to Miami Beach and most central to hotels and Crystal and Gorman's house, though Ft Lauderdale (FLL) often has good deals if you don't mind renting a car and braving the Miami traffic.
Hotel
There are so many great places to stay on Miami Beach making for a short taxi/Uber ride to the Miami Beach Woman's Club. The South Beach Group has several hotels to choose from that are reasonably priced but anything along Collins Avenue between 16th and 21st will be close by. Some nice options in addition to those from South Beach Group are Posh Hotel, the San Juan, Marseilles, Richmond, National, Delano, South Seas, James, Greenview Hotels, Hotel Abbey, Seagull Hotel, and the Albion. We have stayed at a few of these in the past and had good experiences. The Hampton Inn - South Beach 17th street is nearby to the event for those of you with memberships there. Finally, the W Hotel Miami Beach and Hotel 1 are also nearly walking distance from the reception if you are looking to splurge.
